What cables did you use to power the gpu I thought I had it whipped but the six pole connectors I have are too large for the 6 pole on the mb of my 2009 Mac Pro 5,1
 
Those are called mini 6 pin pcie connectors. You'll need those to regular 6 pin (or 8 pin) pcie to power the card.
The same cables are used since G5 era for powering GPUs.
 
Hi,

I recently turned my Mac Pro 1,1 on which has had the GPU upgraded to an MSI 650ti boost (2gb), it used to work and now I get a no signal detected on the monitor, I can VNC the mac and it recognises the GPU and my old GPU still works in the Mac. Noted that I have OS X 10.9.5 installed through macpostfactor. Another note ran Cinebench with my old ATI (521mb) and got 32 fps upgraded it to 650ti and only got 10 fps.

Sounds like you don't have the NVIDIA drivers installed correctly.

Please help me I installed the web driver and cuda driver successfully for my OS 10.9.5 and it says there is no update available but still doesn't work

I have no idea what's going wrong then, sorry. 10.9.5 is ancient, the MacPro1,1 is an ancient machine.

Hi, I read somewhere that the 2 cable connectors on the motherboard are each assigned to a specific PCIe slot (slot 1 or slot 2) if you place a graphics gard in slot 2 instead of slot 1, it might mean you have to use the other connection on the motherboard.

I placed the graphics card in slot 1, but the Nvidia GTX 970 uses 2 6 pin connectors.

Question: Suppose 1 motherboard connection is meant for slot 1 and the other for slot 2, does this mean there is an order in connecting the cables? Should the one be connected left and the other right, or is there absolutely no difference to be expected.

After succesfully placing 4 cards (970, 980, 980 ti) in different Mac Pro models, I am having some stability issues with a GTX 970 in a 5,1 Photoshop CC with distorted images.

Thanks!

New Web Driver out:

https://images.nvidia.com/mac/pkg/367/WebDriver-367.15.10.45f01.pkg

for 10.12.4 (16E195).

No Pascal support.

Out of interest, is there any benefit, performance or otherwise to using the web drivers for a natively supported card like a flashed GTX 680?

Just interested to know if nVidia's driver is better than Apple's or if it's basically the same driver just implemented natively. I play a couple of games through emulation (can't be bothered with Bootcamp and Wineskin works brilliantly well) and extra horsepower is always welcome when you're running an emulator.

The web drivers have been consistently better for OpenGL and OpenCL for the past few years, while Metal is equivalent. So, if you're playing an OpenGL game, you'll probably want to use the web drivers.

A yes-or-no question about non-EFI graphic cards I'd like to double-check with you guys:

My Mac Pro 3,1 / early 2008 more and more often restarts spontaneously. I've done some tests and so I now know it must be a hardware problem, so now I'm trying to figure out what part.

So I pressed the tiny button next to the mini LED's next to the memory riser cards. These give some info on the status. The meaning of the LEDs:

LED 2 Yellow On = Power supply is providing trickle power
LED 7 Green On = EFI has configured the graphics card
LED 8 Green On = All power rails are functioning
LED 9 Green On = EFI is done loading

My 7th LED lights up when I use the old, original 'Mac' card, but if I switch it to the PC graphics card I normally use, it doesn't light up. This is normal and is no indication that there is a problem with my Mac, right?

(Also, if anybody has tips to narrow down the hardware problem I would very much appreciate a PM.)

Is anyone able to update via the Nvidia Driver Manager yet?
Click to expand...

I did. I usually download the OS X Combo Updater and the nvidia installer packages to my computer as a precaution, but I have always updated the nvidia drivers via the control panel and never needed to resort to the install package.

Everything went smoothly this time. Ran OS X updater and updated nvidia drivers and CUDA via the control panels. All is updated and running smoothly.
